Network programming and the main thread

[jacek]

Ok I get it. Smart way of doing things really. So lets say I create a thread with a event-loop to take care of these signals.

That event loop is also necessary to handle the socket.

Is there anything similar for QT4? I heard somewhere that with signals and slots I didnt have to care about these things as they were thread-safe, but I would rather get this confirmed than to discover it after thousands of lines of code.

You can use queued signal-slot connections safely. They were especially designed to handle the communication between threads (in fact they're just a more pleasant version of events).

Just watch out for automatic connections when dealing with threads.
